The Sarno River is regarded as the most polluted river in Italy and possibly all of Europe. Agricultural and sewage runoff frequently contaminates the river and treatment methods are inadequate to handle the pollution. The Sarno River frequently overflows its banks and therefore puts the local population at repeated risk for exposure.
